Serial No. 740,232.

To all whom it may concern Be it known that I, ALFRED H. Moonn, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Methods of Making Railwayllails; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the zurcompanyiugdrawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in methods of making railway rails, the object being to produce a rail which will have great strength, affording great safety.

The invention consists further in the method of making rails of combination steel and iron, the combination being effected in a non-oxidizing atmosphere and consisting in a fusion of the metals, first forming an ingot with steel center and best iron envelop and afterward cutting the ingot in order to expose a steel surface which, when rolled, will form the tread or crown surface of the rail, while the best iron will form a continuous chair for the web and flange of the rail.

In carrying out my process reference is herein made to the accompanying drawings, in which Figure 1 is a perspective View of an ingot having an inner core of steel and an envelop of best iron fused thereto, a portion of the ingot being shown in section. Fig. 2 is a detail view showing the ingot in section, and Fig. 3 is a perspective view of a rail rolled from one of the sections shown in Fig. 2 and having a tread surface of steel and a continuous cha' J' and flange of best iron and fused to the steel core.

In making the rails in accordance with my method, an ingot, previously prepared with an inner core of steel with a uniform percentage of carbon as may be desired to meet different conditions, is provided with an outer envelop of best iron fused thereto which is utilized by first cuttlng the ingot to expose a steel surface which, when the ingot is rolled into a rail, will form the crown or tread surface thereof. It will be understood that the original preparation of the ingot and its being cut and formed into a rail is, done in the same heating. In heating the ingot, the envelop of best iron must be brought to a white heat and at which stage the steel 'lorming the center will be in a semi-liquid or half molten condition. In this conditimi, the steel throws oil carbon which consumes or destroys any of the phosphorus or sulfur contained in the iron, resulting in the production of an ingot equal and superior to the best charcoal iron with an appreciable gain in tensile strength. The ingot is then passed through the rolls with a gentle pressure so as not to burst the envelop and which will cure the steel of porosity. In the treatment of the ingot to cause the proper fusing of the iron and steel, the welding heat of wrought iron is 2700 degrees F., while steel melts at 2552 degrees F.

When the material of the ingot is in proper condition, it is severed longitudinally and centrally and the section of the ingot rolled by any suitable rolling mechanism in such a way that the severed surface will form the trend or crown of the rail while the best iron, which is fused to the steel core, will form a continuous chair or envelop for the web and flange of the rail.

A rail made in accordance with my method will have a hard tread surface.

This application is a continuation of an earlier application bearing Serial No. TliLlQti, tiled July 2.), 1M2.

\Vhat I claim to be new is:
